Illinois Is a No-Fault Divorce State
One of the most important things to understand about divorce in Illinois is that it is a no-fault state. This means that the court does not require either spouse to prove that the other did something wrong in order to grant a divorce.
In earlier times, Illinois courts recognized fault-based grounds for divorce such as adultery or misconduct. Today, that framework no longer exists. The only ground for divorce in Illinois is irreconcilable differences, which simply means that the marriage has broken down irretrievably and there is no reasonable prospect of reconciliation.
As a practical matter, this means that even if your spouse committed adultery or engaged in other troubling behavior, that conduct will generally not affect how property is divided or how other financial matters are resolved in your case. While there may be limited circumstances in which a spouse’s behavior becomes relevant, the no-fault standard is the dominant framework and it is important to understand its implications before you file.
Residency Requirements for Filing in Illinois
Before you can file for divorce in Illinois, you or your spouse must meet the state’s residency requirement. Illinois law requires that at least one spouse have lived in the state for a minimum of 90 days before filing, or have demonstrated a genuine intention to remain in Illinois permanently.
For members of the military who are stationed in Illinois, the law takes a practical approach. Even if a military member has no long-term plans to remain in the state after their assignment ends, their presence during that assignment still satisfies the 90-day residency requirement.
This requirement is generally straightforward for long-term Illinois residents, but it can become a point of contention in cases where spouses live in different states or where one spouse has recently relocated. Understanding how residency is established is an essential first step before filing.
Choosing Where to File: The Importance of Venue
Venue refers to the specific county in which you file your divorce case, and the choice matters more than many people realize. Illinois courts are located in different counties throughout the state, and individual judges in those counties may approach certain issues differently based on their background, experience, and judicial philosophy.
In general, a divorce is filed in the county where one of the spouses resides. However, there are exceptions to this rule that can allow for filing in a different county under certain circumstances. An experienced attorney can evaluate the options available in your situation and advise you on the strategic implications of where your case is filed.

Contested vs. Uncontested Divorce
One of the biggest factors that will determine the cost, duration, and complexity of your divorce is whether it is contested or uncontested.
In an uncontested divorce, both spouses agree on all major issues including property division, child custody, support, and other matters. When parties are aligned, the attorneys can draft a marital settlement agreement, both parties sign it, and the case proceeds to a single court date called a prove-up, at which the judge reviews the agreement and enters judgment. An uncontested divorce can sometimes be resolved in a matter of weeks.
A contested divorce is one where the parties cannot reach agreement on one or more significant issues. In those cases, both sides have the right to a trial. Contested divorces can take months or even years depending on the complexity of the issues and the availability of the assigned judge. Understanding which category your case falls into at the outset will help you set realistic expectations about the road ahead.
